SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 225,397, dated March 9, 1880.

Application filed October 17, 1879.

Sacramento, in the county of Sacramento and partly in section.

State of California, have invented a new and Improved Portable Signal-Lantern, of which the following is a specification.

Figure 1 is a side elevation of the device, Fig. 2 is a perspective view of the lever and shade.

Similar letters of reference indicate corresponding parts.

The invention consists of a portable lantern combined with clock-work mechanism by which flashing or other signals maybe given, so that the number of the signals may convey the desired meaning.

In the drawings, A represents a .lanternframe, which may be of any convenient shape. B is the bulls-eye or glass front of the lantern. O is the lamp. D is'the rocking lever, represented with a balance-weight, E, attached to the end of it, and F is the shade attached to the other end of it, and located in front of the inner face of the bu1ls-eye B.

G represents the mechanism that, through the crown-wheel H or other suitable device, operates to move the shade F alternately back and forth in front of the inner face of the bulls-eye B, so that intermittent flashes of light may proceed therefrom. In this instance the clock work mechanism Gr revolves the wheel H, so that its teeth successively engage with the loop aof the lever D and cause the shade F to move from before the bulls-eye B,

and at each disengagement of the loop cfrom the wheel H the weight E operates to bring the said shade F again before the bulls-eye B.

' This lantern is especially adapted for use as a signal-light on railroads and on shipboard, for by its use the dangers arising from colorblindness may be entirely avoided. Any color of glass maybe used in the lantern, preferably, of course, that color that will farthest transmit the light of the lantern-lamp; but instead of the signal being indicated by the color of the light it will be indicated by the flashes of light, whose duration and frequency will be regulated by the mechanism attached to the lantern.

The mechanism controlling the character of the signals may be operated by springs or weights, or by a combination of the two, and be wound up after the manner of a clock or watch.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- A signal-lantern provided withthe'bullseye B, the lamp 0, the lever D, having weight E, shade F, and loop a, the toothed Wheel H, and the clock mechanism G, all arranged to operate in the manner and for the purpose specified.
